## Long description

Replacement fit dial for GIRO Manifest helmets compatible with RL and TRL Air Fit System retention units. This black size S dial is intended for head circumferences from 51 to 55 cm and provides micro-adjustable control over helmet tension. It allows precise incremental tightening and loosening to restore or improve the helmet's fit without replacing the entire retention assembly. The part is suitable for maintenance, repair, or upgrade of compatible Giro helmets and helps maintain stable, centered positioning on the head during cycling and other activities.
Advantages
The fit dial restores precise, tool-free micro-adjustment of the retention system, enabling a close and secure fit. Its compact design and durable construction match the original fit mechanism to ensure consistent performance and long-term reliability. Installing the replacement dial is a cost-effective solution compared with full assembly replacement and reduces downtime by returning a helmet to usable condition quickly.
Suitable for
Repairing GIRO Manifest helmets with RL or TRL Air Fit System

How to use
To install, remove the existing dial or damaged retention component following the helmet manufacturer's guidance.

Usage recommendations
Check the helmet for visible damage after any impact and replace any compromised components. Use the dial to fine-tune fit prior to each ride and periodically inspect the retention system for wear.
